Blower Door Test in West Long Branch borough, NJ

How Is A Blower Door Test Conducted?

For accurate blower door test in West Long Branch borough, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In West Long Branch borough, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes.
